PATENT JOHN BOULTBEE BROOKS, OF BIRMINGHAM, ENGLAND, ASSIGNOR TO THE J.B. BROOKS dz COMPANY, LIMITED, OF'SAME PLACE.

CYCLE-SADDLE.

SPECIFICATION forming part of Letters Patent No. 589,243, dated August31, 1897.

Application filed December 5, 1896. Serial No. 614,656. (No model.)Patented in England september 30, 1896,110. 21,605.

[ on whom it may concern.-

Be it known that LJOHN BOULTBEE BROOKS,

managing director of the J. B. Brooks & Company, Limited,'a subject ofthe Queen of Great Britain, residing at Criterion WVorks, Great CharlesStreet, in the city of Birmingham, England, have invented certain newand useful Improvements in Cycle-Saddles, of which the following is aspecification, and for which invention I have obtained Letters Patent inGreat Britain bearing date the th day of September, 1896, and numbered21,605. This invention relates to a combined support and securingattachment for cycle-sad- I 5 dles, whereby the boss is more directlyassociated with its support and is capable of mak in g an uninterruptedhorizontal traverse from end to end of the same.

Figure 1 of the accompanying drawings represents in side elevation, withthe saddle-seat in section, a combined saddle-support and securingattachment or boss constructed, arranged, fitted, and working accordingto my invention. In this view the boss is shown at 2 5 the extremeforward end of its support. Fig. 2 is a like view as Fig. 1, but withthe boss coming midway between the two ends, showing howrhe same cantraverse from end to end of the support uninterruptedly or withoutobstruction. Fig. 3 is a top side plan of Fig. 2, but with the seatbroken'away. Fig. 4 is a vertical section of the attachment upon thedotted line as, Fig. 2, showing the relative positions of the assembledcomponent parts of the combined support and boss. Fig. 5 represents sideand end elevations and a plan of the sliding block which constitutes thebody of the boss and whose foot is of the same cross-section as theinside of the troughed support, which is shown separately in side andend elevations and plan in Fig. 6. Fig. 6 illustrates detached details.

The same letters of reference indicate corresponding parts in theseveral figures of the drawings.

Surmounting the seat-pillar a is a horizontal and trough-sectionedsupport bar or bed a, having overhanging and yielding sides a and withinwhichalike-sectioned foot I) of a '50 sliding carrier-block or bodypartb of the boss longitudinally traverses or slides uninterruptedly fromend to end of the said troughed section support or bar. The upper end of.this said body part, which is of a breadth about equal to that of theopen top a of the trough, is transversely pierced with a square hole 17wherethrough the square body 0 of a central screw-ended pin 0 passes,with the ends 0 overhanging the inclined sides of the said supportorbed, and upon each of which a gripping-cheek d, an insideframe-wire-gripping washer e, and an outside frame-wiregrippingwasherfare strung and are brought togetherand against the side of the solidbody part b by a screw-nut 9. Now the grippingcheeks (Z haveinwardly-projecting bearing ribs or lugs 61', which impinge upon theopposite side faces 19 of the body part b, and inclined lowerbearing-surfaces (Z which impinge against the out-sides of the inclinedor overhanging and yielding walls a of the support a, which parts a areforced slightly inward and against the inclined sides Z1 of the foot Z)of the said bodyb on the nuts 9 on the ends of the pin 0 being screwedup. These cheeks d have central square eyes 61 of a depth rather greaterthan that of the pin, so

as to admit of the same slightly rocking upon the lugs as centers, inorder to allow the lower bearing-surfaces d to follow up the slightchange of angle or plane which occurs in the overhanging sides a whenthe same are pressed inward upon the foot of the block.

The outer faces of the gripping-cheeks have rocking clearances d andcollars (1 upon which latter the frame-gripping washers 6, having holes6 through them and keepgrooves 6 upon their outer faces for thereception of the frame-wires h of the saddle, take and are capable ofrotation thereon. The inner faces of these washers e have hardened teeth6 which embed themselves When forced home into the softer metal of theopposed faces of the gripping-cheeks.

The outer frame-washers f, which have 9 5 holes f through theiriniddles, have keepgrooves f upon their inner faces for the reception ofthe frame-wires h and take and rotate upon collars g of the nuts g.

When the parts of the boss and its support are assembled, as in Figs. 1,2, 3, and 4, With one or both of the nuts 9 slackened, the boss can beslid or made to uninterruptedly traverse from end to end or to any partof the bed-support a, and any desired tilt can be given to the saddle11, carried by the framerods h. By now screwing up either one or otheror both of the nuts 9 the distance between them is diminished and thewhole of the assembled parts threaded upon the pin are drawn togetherwith the frame-rods h firmly clamped between the opposed faces of thepairs of washers c and f, while the teeth of the washers e are embeddedinto the outer faces of the gripping-cheeks d, which in their turn areforcibly impressed against the two opposite sides of the solid body partb and the inclined lower bearing-surfaces against the outward-presentedfaces of the yielding sides (0 of the bed-rest a. By now furtherscrewing up the nut or nuts the gripping-cheeks are made to slightlyturn inward upon their lugs as centers and so forcibly press inwardtheir lower parts, whereby the said sides are gathered in and nippedbetween the lower surfaces of the gripping-el1eeks and the foot of theblock.

sides and fitted with an internal support in the form of a sliding blockor body or other part of the attachment-boss and with gripping-cheeks,strung upon a pin orequivalent and taking a bearing upon the outer sidesof the said bed, the said yielding sides being thus nipped and clampedbetween the internal block or support and the outer grippingcheeks,substantially as and for the purpose described and set forth.

2. A support and attachment-boss for cyclesaddles consisting of aseat-pi11ar,surn1ounted by a trough-sectioned bed, having yielding sidesand fitted with an internal support in the form of a sliding block orbody or other part of the attachment-boss, and with gripping-cheeksstrung upon a pin or equivalent and taking a bearing upon the outersides of the said bed, which are thus nipped and clamped between theinternal block or support and the outer gripping-cheeks, and with aframe-clamping washer or washers and a securing nut or nuts also takingupon the ends of the pin o equivalent, Substantially as described andset forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
